rw active + reactive power (watt＋var)
rw system active power (watt)
r reactive power (var)
these transducers convert the active power or reactive power of a single-phase or three-phase system with balanced or unbalanced loads.
the output signals are isolated load independent dc current or dc voltage, representing the measured value of the active and reactive power.特性? high accuracy ±0.2%rd ±0.1%ro
? precision measurement even for distorted waves
? uses time division multiplier for watt and var
? high immunity to external noise
? wide selection of input and output range
? quick and easy mounting
